Authentic Llandaff Leek & Cheese Rarebit

Sauté finely chopped leeks in butter until very soft. Make a thick sauce by melting butter with flour and gradually whisking in a splash of robust Welsh ale.

Stir in grated mature cheddar, mustard powder, and a dash of Worcestershire sauce until melted and smooth.

Fold in the softened leeks.

Toast thick slices of crusty bread, then heap the cheese mixture on top.

Grill until bubbling and golden-brown.

A refined Cathedral city version of the ultimate Welsh comfort food.
